MaltParser cheat mode

If you train MaltParser using the learnwo flowchart in place of learn, it does all the same things, except that it writes out the sentences as it reads them in.

This means that if you have, ahem, misformatted any of your input, you can see exactly which misformatting MaltParser is complaining about, because it will be in the first sentence that hasn’t been written to stdout.
